Flickering of screen and then laptop goes to sleep

[CHICHAYSKIE]

Since i bought my laptop 1 year ago, a few weeks later after i bought it, the screen flickers randomly. Recently it flickers alot more than usual and now and after it flickers, it randomly goes sleep mode (i think, cos it doesnt literally turns off. If i click the spacebar it goes to the log in screen). It does this alot of times even if im just on ms word or google chrome. 

Pls help. Im out of my warranty and prefer to fix it my self if its posssible.

@CHICHAYSKIE,

Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community! I came across your post and wanted to assist you. I understand you are having issues with the screen flickering on your HP notebook. Don't worry we'll work together to find a solution for you.

To provide you with an accurate solution, I'll need a few more details:

Could you provide me with the exact model of the PC? Use this link to find it:  https://support.hp.com/in-en/document/c03754824  (Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).

Have you recently made any changes on the PC before the issue started?

Did you check for any damage on the PC?

Have you tried to update the drivers? Did you try to update the Bios.

Have you checked if the issue persists even in the Bios screen?

Did this happen after upgrading to Windows 10? If so, have you gone through the steps suggested in this support document.

Let's try one issue at a time: 

In the meantime, let's start off by performing a Hard reset on the Notebook:

Step 1: Performing a hard reset

Resetting the computer can resolve many issues that cause a blank screen. Use the steps in Performin...

Step 2: Connecting an external monitor to test the display

The notebook screen display might remain black when there is a corrupted graphics driver or a problem with the LCD display backlight. To test the display, attach an external monitor and restart the computer. Testing with an external display is helpful if the notebook display is black but you can hear sounds; such as fans, spinning drives, or beep tones that indicate the computer is operating.

Step 3: ​​​​Boot the computer into the Bios screen and check if the screen flickers.

1. Turn off your computer
2. Make sure you have connected the power cable
3. Turn on your notebook, as it is starting press the  F10 button repeatedly

Once you are in the BIOS, if the screen flickers, it is likely a hardware failure. The next two steps may resolve the issue. The first one is to do a hard reset. I have included the document 'Performing a Hard Reset or Forced Reset'. The next and final step is to perform a BIOS update. I have included the information here for you 'Updating the BIOS' as well as updating the graphics card drivers from our HP Support website, using this link.

If the issue persists, I would suggest the next step would be to run a test an extensive test on the graphics card which is listed under Component test

You could also try to run an extensive test on the system. (Please capture the failure ID for further assistance).

For more assistance, please follow the steps suggested in the support document for - HP Notebook and All-in-One PCs - Troubleshooting Screen Issues (Windows 10, 8, 7)

Please let me know if this resolves the issue, or if you require further assistance!

Eagerly waiting for your response!

I hope you have a good day ahead,
